MODE FOR CARRYING OUT THE INVENTION

Hereinafter, a mode for carrying out the present disclosure (hereinafter, referred to as an embodiment) will be described.

<<Outline of Autonomous Moving Body 10>>

FIG. 1 is a diagram illustrating a hardware configuration example of an autonomous moving body 10 according to an embodiment of the present disclosure.

First, an outline of the autonomous moving body 10 will be described. The autonomous moving body 10 is an information processing apparatus that executes circumstances estimation based on collected sensor information, and autonomously selects and performs various motions in accordance with the situation. One of the features of the autonomous moving body 10 is that the autonomous moving body autonomously executes an operation estimated to be optimal for each situation, unlike a robot that simply performs an operation according to a user's instruction command.

Therefore, there is a case where the autonomous moving body 10 according to an embodiment of the present disclosure may not intentionally execute a motion corresponding to the user's instruction or may execute another behavior different from the motion depending on the situation. The situation described above corresponds to, for example, a case where the safety of the user, the autonomous moving body 10, or the surrounding environment is impaired in a case where a motion corresponding to a user's instruction is performed, a case where the autonomous moving body 10 prioritizes another desire (instinct) such as charging processing, and the like.

Furthermore, there is a case where the autonomous moving body 10 intentionally does not follow the user's instruction to attempt to trigger the interest of the user or attempt to transmit its own feeling or the state of the hardware to the user.

On the other hand, the autonomous moving body 10 has a strong desire (instinct) to be loved by the user. Therefore, the autonomous moving body 10 repeatedly executes a motion corresponding to a user's instruction in order to please the user, or learns a motion that the user likes to spontaneously execute the motion even in a case where there is no instruction.

As described above, the autonomous moving body 10 according to an embodiment of the present disclosure determines and executes the autonomous motion by comprehensively determining a desire, a feeling, a surrounding environment, and the like, similarly to an animal including a human. In the point described above, the autonomous moving body 10 is clearly different from a passive apparatus that executes a corresponding operation or processing on the basis of an instruction.

The autonomous moving body 10 according to an embodiment of the present disclosure may be an autonomous moving robot that autonomously moves in a space and executes various motions. The autonomous moving body 10 may be, for example, an autonomous moving robot that has a shape imitating a human being or an animal such as a dog and motional ability. Furthermore, the autonomous moving body 10 may be, for example, a vehicle or another apparatus capable of communicating with the user. The level of shape, ability, desire, and the like of the autonomous moving body 10 according to an embodiment of the present disclosure can be appropriately designed according to a purpose and a role.

<<Hardware Configuration Example of Autonomous Moving Body 10>>

Next, a hardware configuration example of the autonomous moving body 10 will be described. Note that, in the following, a case where the autonomous moving body 10 is a dog-type quadruped walking robot will be described as an example.

As illustrated in FIG. 1 , the autonomous moving body 10 is a dog-type quadruped walking robot having a head, a body, four legs, and a tail. Furthermore, the autonomous moving body 10 includes two displays 510 on the head.

Furthermore, the autonomous moving body 10 includes various sensors. The autonomous moving body 10 includes, for example, a microphone 515, a camera 520, a time of flight (ToF) sensor 525, a motion sensor 530, a position-sensitive detector (PSD) 535 sensor, a touch sensor 540, an illuminance sensor 545, a sole button 550, and an inertia sensor 555.

(Microphone 515)

The microphone 515 has the function of collecting surrounding sound. The sound described above includes, for example, an utterance of the user and surrounding environmental sounds. The autonomous moving body 10 may include, for example, four microphones on the head. By providing a plurality of microphones 515, it is possible to collect sounds generated in the surroundings with high sensitivity and to realize a fix of a sound source.

(Camera 520)

The camera 520 has the function of imaging the user and the surrounding environment. The autonomous moving body 10 may include, for example, two wide-angle cameras at the nose tip and the waist. In this case, the wide-angle camera arranged at the nose tip captures an image corresponding to a front visual field of the autonomous moving body (that is, the visual field of the dog), and the wide-angle camera of the waist captures an image of a surrounding region centered on the upper side. The autonomous moving body 10 can extract a characteristic point of the ceiling and the like on the basis of an image captured by the wide-angle camera arranged on the waist, for example, and can realize simultaneous localization and mapping (SLAM).

(ToF Sensor 525)

The ToF sensor 525 has the function of detecting a distance to an object present in front of the head. The ToF sensor 525 is provided at the nose tip of the head. According to the ToF sensor 525, distances to various objects can be detected with high accuracy, and a motion according to a relative position with respect to a target including a user, an obstacle, or the like can be realized.

(Motion Sensor 530)

The motion sensor 530 has the function of sensing the whereabouts of the user, a pet raised by the user, or the like. The motion sensor 530 is, for example, arranged on the chest. According to the motion sensor 530, by sensing a moving object present ahead, it is possible to realize various motions with respect to the moving object, for example, motions according to feelings such as interest, fear, surprise, and the like.

(PSD Sensor 535)

The PSD sensor 535 has the function of acquiring a situation of a floor surface ahead of the autonomous moving body 10. The PSD sensor 535 is, for example, arranged on the chest. According to the PSD sensor 535, the distance to the object present on the floor surface ahead of the autonomous moving body 10 can be detected with high accuracy, and a motion according to a relative position with respect to the object can be realized.

(Touch Sensor 540)

The touch sensor 540 has the function of sensing a touch by the user. The touch sensor 540 is arranged at a portion where the user is likely to touch the autonomous moving body 10, for example, such as the top of the head, under the chin, or the back. The touch sensor 540 may be, for example, a capacitive or pressure-sensitive touch sensor. According to the touch sensor 540, it is possible to sense a touch action such as touching, stroking, hitting, pushing, or the like by the user, and it is possible to perform a motion according to the touch action

(Illuminance Sensor 545)

The illuminance sensor 545 detects illuminance of a space in which the autonomous moving body 10 is located. The illuminance sensor 545 may be arranged, for example, at the base of the tail or the like on the back surface of the head. According to the illuminance sensor 545, it is possible to detect surrounding brightness and execute a motion according to the brightness.

(Sole Button 550)

The sole button 550 has the function of sensing whether or not the bottom of a leg portion of the autonomous moving body 10 contacts the floor. For this purpose, the sole buttons 550 are arranged on each portion corresponding to the paw pads of the four leg portions. According to the sole button 550, it is possible to sense contact or non-contact between the autonomous moving body 10 and the floor surface, and, for example, it is possible to grasp that the autonomous moving body 10 has been lifted in the arms of the user and the like.

(Inertia Sensor 555)

The inertia sensor 555 is a six-axis sensor that detects physical quantities, such as speed, acceleration, and rotation of the head or the body. That is, the inertia sensor 555 detects acceleration and angular velocity on the X axis, the Y axis, and the Z axis. The inertia sensor 555 is arranged at each of the head and the body. According to the inertia sensor 555, movements of the head and the body of the autonomous moving body 10 can be detected with high accuracy, and the motion control according to the situation can be realized.

An example of the sensor included in the autonomous moving body 10 according to an embodiment of the present disclosure has been described above. Note that the configuration described above described with reference to FIG. 1 is merely an example, and the configuration of the sensor that can be included in the autonomous moving body 10 is not limited to such an example. The autonomous moving body 10 may further include, in addition to the configuration described above, for example, various communication devices and the like including a temperature sensor, a geomagnetic sensor, and a Global Navigation Satellite System (GNSS) signal receiver. The configurations of sensors that the autonomous moving body 10 includes may be flexibly varied according to the specification and use.

Next, a configuration example of a joint portion of the autonomous moving body 10 will be described. FIG. 2 is a configuration example of an actuator 570 included in the autonomous moving body 10 according to an embodiment of the present disclosure. The autonomous moving body 10 according to an embodiment of the present disclosure has 22 degrees of freedom of rotation in total including, in addition to degrees of freedom of rotation in rotating portions illustrated in FIG. 2 , two degrees of freedom of rotation in each of the pair of ears and the tail portion, and one degree of freedom of rotation in the mouth.

For example, the autonomous moving body 10 has three degrees of freedom in the head and thus enables both motions of nodding and tilting the head. Furthermore, the autonomous moving body 10 enables the realization of natural and flexible motions closer to those of a real dog by reproducing swing operations of the waist using the actuator 570 provided at the waist portion.

Note that the autonomous moving body 10 according to an embodiment of the present disclosure may realize the 22 degrees of freedom of rotation described above by combining a single-axis actuator and a two-axis actuator for example. For example, single-axis actuators may be used for the elbows and knees of the leg portions, and two-axis actuators may be used for the shoulders and the bases of thighs, respectively.

FIGS. 3 and 4 are diagrams for explaining a motion of the actuator 570 included in the autonomous moving body 10 according to an embodiment of the present disclosure. Referring to FIG. 3 , by rotating an output gear using a motor 575, the actuator 570 enables a movable arm 590 to be driven at a given rotational position and a rotational speed.

Referring to FIG. 4 , the actuator 570 includes a rear cover 571, a gearbox cover 572, a control board 573, a gearbox base 574, the motor 575, a first gear 576, a second gear 577, an output gear 578, a detection magnet 579, and two bearings 580.

The actuator 570 may be, for example, a magnetic spin-valve giant magnetoresistive (svGMR). The control board 573 causes the motor 575 to rotate on the basis of the control by a main processor, so that power is transmitted to the output gear 578 via the first gear 576 and the second gear 577, and accordingly the movable arm 590 can be driven.

Furthermore, the position sensor included in the control board 573 detects a rotation angle of the detection magnet 579 that rotates in synchronization with the output gear 578, whereby the rotation angle, that is, the rotational position of the movable arm 590 can be detected with high accuracy.

Note that the magnetic svGMR employs a non-contact system and thus has excellent durability and the magnetic svGMR is used in a GMR saturated area and thus has an advantage in that effects of signal variations resulting from variations in distance between the detection magnet 579 and the position sensor are small.

The configuration example of the actuator 570 included in the autonomous moving body 10 according to an embodiment of the present disclosure has been described above. According to the configuration described above, bending and stretching motions of the joint portions included in the autonomous moving body 10 can be controlled with high accuracy, and the rotational positions of the joint portions can be accurately detected.

The display 510 has the function of visually expressing motions of eyes and feelings of the autonomous moving body 10. As illustrated in FIG. 5 , the display 510 can express motions of eyeballs, pupils, and eyelids according to a feeling and motion. The display 510 produces natural motions close to those of an existing animal such as a dog by intentionally not displaying texts, symbols, images not related to eyeball movements, and the like.

Furthermore, as illustrated in FIG. 5 , the autonomous moving body 10 includes two displays 510 r and 5101 corresponding to each of the right eye and the left eye. The displays 510 r and 5101 are realized by, for example, two independent organic light emitting diodes (OLEDs). According to the OLED, it is possible to reproduce the curved surface of the eyeball, and it is possible to realize a more natural exterior compared to the case where a pair of eyeballs is expressed using a single planar display or the case where the two eyeballs are expressed respectively using two independent planar displays.

As described above, according to the displays 510 r and 5101, it is possible to express the line-of-sight and feelings of the autonomous moving body 10 as illustrated in FIG. 5 with high accuracy and flexibility. Furthermore, the user can intuitively grasp the condition of the autonomous moving body 10 from motions of eyeballs displayed on the display 510.

The hardware configuration example of the autonomous moving body 10 according to an embodiment of the present disclosure has been described above. According to the configuration described above, as illustrated in FIG. 6 , by controlling the motions of the joint portions and the eyeballs of the autonomous moving body 10 with high accuracy and flexibility, it is possible to realize motions and expressions of feeling closer to those of an existing living thing.

<<Another Mode of System Configuration Example>>

First, another mode of a configuration example of a system according to an embodiment of the present disclosure will be described with reference to the drawings. FIG. 11 is an explanatory diagram illustrating a configuration example of an information processing system according to an embodiment of the present disclosure. Hereinafter, a configuration example of the information processing system according to an embodiment of the present disclosure will be described with reference to FIG. 11 . Note that, in FIGS. 11 to 13 , a projection apparatus will be used as an example of the information processing terminal 30.

As illustrated in FIG. 11 , an information processing system according to an embodiment of the present disclosure includes a projection apparatus 100 a as an information processing apparatus having an output function and an input function. In the example illustrated in FIG. 11 , the projection apparatus 100 a displays information on a top surface 141 a (tabletop) of a table 140 a and causes the user to operate the information displayed on the top surface 141 a. A method of displaying information on the top surface 141 a of the table 140 a as illustrated in FIG. 11 is also referred to as “projection type”.

The projection apparatus 100 a is provided above the table 140 a, for example, in a state of being suspended from the ceiling. That is, the projection apparatus 100 a is provided isolatedly from the table 140 a to be a target on which information is displayed.

Furthermore, the projection apparatus 100 a includes an input function (input unit 110 a) for inputting content of the user's operation on display information on the top surface 141 a (tabletop), the shape of an object placed on the table 140 a, and the like. As the input unit 110 a of the projection apparatus 100 a, for example, a camera that captures an image of the table 140 a with one lens, a stereo camera that can capture an image of the table 140 a with two lenses and record information in the depth direction, a microphone (hereinafter, referred to as a microphone) for collecting sound uttered by the user and surrounding environmental sound, or the like is used.

In a case where a camera that captures an image of the table 140 a with one lens is used as the input unit 110 a, the projection apparatus 100 a can detect an object placed on the table 140 a by analyzing the image captured by the camera. Furthermore, in a case where a stereo camera is used as the input unit 110 a, for example, a visible light camera, an infrared camera, or the like can be used as the stereo camera. In a case where the stereo camera is used, the projection apparatus 100 a can acquire depth information. By acquiring the depth information, the projection apparatus 100 a can detect a hand or an object placed on the table 140 a, for example, distinctively from the pattern of the top surface 141 a or the pattern of the table cloth. Furthermore, by acquiring the depth information, the projection apparatus 100 a can detect touch or approach of a hand of the user to the top surface 141 a of the table 140 a or detect separation of the hand from the top surface 141 a. Note that, in the following description, a user touching or approaching an information display surface (here, the top surface 141 a) with an operating body such as a hand is also collectively referred to simply as “touch”.

Furthermore, in a case where a microphone is used as the input unit 110 a, a microphone array for collecting sound in a specific direction can be used as the microphone. The projection apparatus 100 a may adjust a sound collection direction of the microphone array to any direction.

Hereinafter, a case where an operation by the user is detected from an image captured by the input unit 110 a will be mainly described, but the present disclosure is not limited to the related example. The operation by the user may be detected by a touch panel that is provided on the top surface 141 a of the table 140 a that detects the touch of a finger and the like of the user. Furthermore, the user operation that can be acquired by the input unit 110 a may include, in addition, for example, a stylus operation on an information display surface, a gesture operation on a camera, and the like.

Furthermore, the projection apparatus 100 a has an output function (output unit 130 a) that displays information on the top surface 140 a (tabletop) of the table 141 a or outputs sound. As the output unit 130 a, for example, a projector, a speaker, or the like is used.

In a case where the output unit 130 a includes a projector, the output unit 130 a projects information on the top surface 140 a of the table 141 a. In a case where the output unit 130 a includes a speaker, the output unit 130 a outputs sound on the basis of a sound signal. The number of speakers may be one or plural. In a case where the output unit 130 a includes a plurality of speakers, the projection apparatus 100 a can limit the speakers that output sound or adjust the direction in which sound is output.

Furthermore, in a case where the projection apparatus 100 a is a projection type as illustrated in FIG. 11 , the output unit 130 a may include an illumination device. In a case where the illumination device is included, the projection apparatus 100 a can control a state of turning on or off the illumination device and the like on the basis of the content of the information input by the input unit 110 a.

The user who uses a projection system as illustrated in FIG. 11 can place his or her finger or the like on the top surface 141 a to operate information displayed on the top surface 141 a of the table 140 a by an output function (output unit 130 a) of the projection apparatus 100 a.

Note that, although not illustrated in FIG. 11 , another device may be connected to the projection apparatus 100 a. For example, a mobile device such as a smartphone or a tablet terminal possessed by the user may be directly connected to the projection apparatus 100 a by wireless connection, or may be connected to a server or the like via a network.

In the present disclosure, in a case where the autonomous moving body 10 moves on the table 140 a, a figure indicating a state of feeling is irradiated (projected) on the tabletop in a projection manner according to the position and the state of feeling of the autonomous moving body 10. Note that a specific irradiation (projection) method will be described later.

In the present disclosure, the mode of the information processing system is not limited to that illustrated in FIG. 11 . FIGS. 12 to 13 are diagrams illustrating examples of another mode of the information processing system according to an embodiment of the present disclosure.

FIG. 12 is a diagram illustrating another configuration example of the information processing system according to an embodiment of the present disclosure, in which a projection apparatus 100 b irradiates information from under a table 140 b to display the information on a top surface 141 b of the table 140 b. In the example illustrated in FIG. 12 , the projection apparatus 100 b includes an output unit 130 b realized by a projector. Furthermore, in the information processing system illustrated in FIG. 12 , the top surface 141 b of the table 140 b serving as the information display surface is formed of a transparent material such as a glass plate or a transparent plastic plate. A method of displaying information on the top surface 141 b by irradiating information from under the table 140 b as illustrated in FIG. 12 is also referred to as “rear projection type”. Furthermore, in the example illustrated in FIG. 12 , an input unit 110 b realized by a touch panel is provided on the top surface 141 b of the table 140 b and detects a user operation on the information displayed on the top surface 141 b. Note that the input unit 110 b is not limited to the configuration provided on the top surface 141 b, and for example, the input unit 110 b realized by a camera may be provided below the table 140 b isolatedly from the table 140 b, or may be included in the projection apparatus 100 b.

In the present disclosure, in a case where the autonomous moving body 10 moves on the table 140 b, a figure indicating the state of feeling is irradiated (projected) from under the table 140 b in the rear projection type according to the position and the state of feeling of the autonomous moving body 10. Note that a specific irradiation (projection) method will be described later.

FIG. 13 is a diagram illustrating another configuration example of the information processing system according to an embodiment of the present disclosure. FIG. 13 illustrates a state in which an information processing apparatus 100 c realized by a touch panel type display is placed on a top surface 141 c of a table 140 c. As described above, in a case where the touch panel type display is used, an input unit 110 c and an output unit 130 c can be configured as the touch panel type display. That is, in the information processing system illustrated in FIG. 13 , the information display surface is the touch panel type display. As illustrated in FIG. 13 , a method of displaying information on a touch panel type display placed on the top surface 141 c is also referred to as “flat arrangement display type”. In the information processing system illustrated in FIG. 13 , a camera for detecting the position of the user may be provided above a touch panel type display.

In the present disclosure, in a case where the autonomous moving body 10 moves on the top surface 141 c, a figure indicating the state of feeling is displayed on the touch panel display 130 c according to the position and the state of feeling of the autonomous moving body 10. Note that a specific display method will be described later. Furthermore, the present disclosure is also applicable to a display that the output unit 130 c does not have a touch panel function, and is not limited to the touch panel function.

<<Outline of Display/Irradiation (Projection) Example>>

Hereinafter, application examples according to the present embodiment will be described in detail with specific examples.

FIG. 14 is an explanatory diagram illustrating an example in which the autonomous moving body 10 moves on the table 140 b as illustrated in FIG. 12 . In FIG. 14 , in conjunction with the position of the autonomous moving body 10 and the state of feeling of the autonomous moving body 10, the projection apparatus 100 b including the output unit 130 b realized by the projector irradiates (projects) a state as a figure R1 to the lower side of the autonomous moving body 10. In this case, the position of the autonomous moving body 10 is sensed by a sensor (that is built in the projection apparatus 100 b or is provided separately), and the projection apparatus 100 b acquires a parameter (feeling parameter) indicating a feeling of the autonomous moving body 10 via the network. Then, the projection apparatus 100 b performs irradiation (projection) such that the center (or the center of gravity) of the figure R1 is located in the vicinity of the center (or the center of gravity) of the autonomous moving body 10 according to the sensed position and the acquired feeling parameter. Therefore, the figure R1 moves according to the change in the position of the autonomous moving body 10, and the display form (characteristics, i.e., shape, size, color, and the like) changes in conjunction with the change in the feeling of the autonomous moving body 10. Note that the rear projection type has an advantage that a shadow of the autonomous moving body 10 is not displayed along with the irradiation (projection) as compared with the projection type.

FIG. 15 is a diagram illustrating another example in which the autonomous moving body 10 moves. In FIG. 15 , the state of the figure R1 to be irradiated or displayed is different according to the state of feeling of the autonomous moving body 10. For example, in a case where the autonomous moving body 10 has a sad feeling, blue is colored in a state where the circle is deformed. Note that not only the figure R1 but also the name of the feeling (sadness) may be irradiated (projected) or displayed so as to be superimposed on the figure R1 .

FIG. 16 is a diagram illustrating another example in which the autonomous moving body 10 moves. FIG. 16 illustrates a state in which another autonomous moving body M that supports the autonomous moving body 10 follows the autonomous moving body 10 while sensing the condition (motion, movement, and the like) of the autonomous moving body 10. In this case, another autonomous moving body M acquires position information by sensing the position of the autonomous moving body 10 with a sensor and acquires a parameter (feeling parameter) indicating a feeling of the autonomous moving body 10 via the network, thereby irradiating (projecting) a figure R1 and a figure R2 such that the center (or the center of gravity) of the figure is located in the vicinity of the center (or the center of gravity) of the autonomous moving body 10 in conjunction with the position of the autonomous moving body 10 and the state of feeling of the autonomous moving body 10. Note that the figure R2 is a figure (guide) indicating a reference of the shape of the figure. By irradiating (projecting) the figure R2 , a change in the display form of the figure R1 can be easily visually recognized. Note that it is sufficient to irradiate the figure R2 as necessary. Note that the configuration of the other autonomous moving body M is similar to that of the information processing terminal 30 described in FIG. 10 .

FIG. 17 illustrates a state in which the information processing terminal 30 uses augmented reality in which information is superimposed while capturing an image of the real world using a mounted camera in a living room having a television VO. In FIG. 17 , in a case where imaging the autonomous moving body 10, the information processing terminal 30 acquires the feeling parameter of the autonomous moving body 10 via the network, acquires the position (or distance) of the autonomous moving body 10 using a mounted sensor (depth sensing, TOF sensing, infrared sensing, and the like using a camera), and displays the figure R1 and the figure R2 on the display screen displayed at the time of imaging such that the center (or the center of gravity) of the figure is located in the vicinity of the center (or the center of gravity) of the autonomous moving body 10 in conjunction with the position of the autonomous moving body 10 and the state of feeling of the autonomous moving body 10. As described above, the present disclosure can be used as a display form of augmented reality.

FIG. 18 is an example in which a 3D model imitating an exterior, sound (cry), or the like of the autonomous moving body 10 possessed by the user is displayed as an avatar AV on the display described in FIG. 13 or the display screen of the information processing terminal 30. Here, the exterior described above includes, for example, colors such as an eyeball (pupil, iris, and the like), a body-color, and the like of the autonomous moving body 10. Similarly to the example of the augmented reality of FIG. 17 , in a case where using the application in which the avatar AV is displayed, the information processing terminal 30 acquires the feeling parameter of the autonomous moving body 10 via the network, acquires the position (or distance) of the autonomous moving body 10 using the mounted sensor (depth sensing, TOF sensing, infrared sensing, and the like using a camera), and displays the figure R1 and the figure R2 on the display screen of the application such that the center (or the center of gravity) of the figure is located in the vicinity of the center (or the center of gravity) of the autonomous moving body 10 in conjunction with the position of the autonomous moving body 10 and the state of feeling of the autonomous moving body 10. As described above, the present disclosure can be applied to various applications related to the autonomous moving body 10.

<<Specific Example of Display/Irradiation (Projection) Example>>

First, a concept of the present disclosure will be described. The present disclosure focuses on presenting feeling to the user more intuitively and with high responsivity in a case where the feeling changes temporally, such as an interaction with the user and a motion (stroking the head, or the like) performed on the autonomous moving body 10 by the user, instead of presenting the feeling by an expression, an interaction, a motion, or the like when feeding back the feeling to the user (person) considering the autonomous moving body 10 whose motion changes with feeling as a target. Conventionally, the user has been got to associate feeling through an expression of a face imitating a person or an animal, a voice or a cry, or a motion of the autonomous moving body 10 itself. Furthermore, the feeling has merely been quantified, a name and number of the feeling have merely been presented in text, graph, or the like. The present disclosure is characterized in that a state of feeling is presented to a user in a display form in which the feeling can be more intuitively understood.

In the present disclosure, in consideration of the relationship between the change in the position and the change in the feeling accompanying the movement of the autonomous moving body 10, the change in the feeling is expressed by the change in the state of the figure that is likely to be associated by a person (change in shape, speed of change in shape, change in size, peed of change in size, change in color, speed of change in color, change in the combination of colors, speed of change in the combination of colors, change in gradation, speed of change in gradation, and the like) while causing to follow the change in the position. With such expression, the user who confirms the autonomous moving body 10 can intuitively associate the state of feeling of the autonomous moving body 10 by making association as required and can easily grasp the state of the feeling.

FIG. 19 illustrates an appearance of the figure R1 to be irradiated (projected) or displayed as described above. The display form (shape, size, color, gradation, and the like) of the figure R1 changes according to the position of the autonomous moving body 10 and the feeling condition (the content of the feeling parameter) of the autonomous moving body 10. In the present embodiment, an example in which a display form is changed based on a circle (suggestive of life, stability, and the like) will be described. In FIG. 19 , feeling and color (gradation) are associated, and a line inside a circle indicates a change point of color (the line itself is not displayed because of gradation originally). For example, from the left, the color inside the circle changes from green, yellow, and light blue. As described above, in a case where displaying a plurality of feelings, the feeling condition of the autonomous moving body 10 is displayed by color gradation or the like. Note that it is also possible to display one feeling by a single color. Note that a specific relationship between a feeling and a display form will be described later.

FIG. 20 illustrates an example of a case where the shape and size of the figure R1 change as a change in the display form. The size of the figure R1 changes depending on the strength of the feeling (the magnitude of the feeling parameter value indicating the feeling). For example, in a case where the figure R1 is a figure of the same shape (the same feeling), the size of the figure R1 increases as the feeling becomes stronger. Similarly, in a case where the figure R1 is a figure of the same shape (the same feeling), the size of the figure R1 decreases as the feeling becomes weaker. As described with reference to FIG. 16 , the figure R2 is a figure (guide) indicating a reference of the shape of the figure. By displaying this figure R2 , a change in the shape of the figure R1 can be easily visually recognized. Note that it is sufficient to display the figure R2 as necessary.

FIG. 21 illustrates an example of a case where the shape of the figure R1 changes as a change in the display form.

Graphic A of FIG. 21 illustrates a form associated with joy. Graphic B of FIG. 21 illustrates a form associated with anticipation. Graphic C of FIG. 21 illustrates a form associated with anger. Graphic D of FIG. 21 illustrates a form associated with disgust. Graphic E of FIG. 21 illustrates a form associated with sadness. Graphic F of FIG. 21 illustrates a form associated with surprise. Graphic G of FIG. 21 illustrates a form associated with fear. Graphic H of FIG. 21 illustrates a form associated with trust. As described above, the shape of the figure R1 changes depending on the content of the feeling (the content of the feeling parameter indicating the feeling). Note that, In FIG. 21 , black on the outer periphery of the figure R1 is illustrated to facilitate understanding of the shape of the figure R1 .

FIG. 22 illustrates a correspondence relationship between the feeling parameter that is the content (type) of the feeling of the autonomous moving body 10 and the display form of the figure R1 . For example, the joy of the feeling parameter A corresponds to the figure R1 that has a stable circle (circle) shape colored in yellow and repeats enlargement and reduction with a rhythm suggestive of anticipation. Furthermore, the surprise of the feeling parameter F corresponds to the figure R1 that has a shape that looks like a balloon colored in light blue is popped and is temporarily fixed without changing the size so as to be suggestive of surprise.

FIG. 23 illustrates a correspondence relation between the feeling parameter that is the content (type) of the feeling of the autonomous moving body 10 and the display form of the figure R1 . In FIG. 23 , compared to FIG. 22 , a pair of feelings in which two feelings (feeling parameters) pair up is added. The pair of feelings is a generic term for grouping two feeling parameters that are less likely to be compatible (likely to be a place to play a game) into a pair. In this case, it is assumed that just either one of the feeling parameters having a high possibility of being in the game in the pair of feelings only becomes active (has a large value). Therefore, in a case where the display form of the figure R1 is changed using a plurality of feeling parameters, colors and shapes corresponding to the number of pairs of feelings are used.

FIG. 24 illustrates an example of changing the display form of the figure R1 using the pair of feelings and the plurality of feeling parameters in FIG. 23 . For example, in a case where the feeling parameter E is active (or the value of the parameter is large) for the pair of feelings AE, the feeling parameter F is active (or the value of the parameter is large) for the pair of feelings BF, the feeling parameter G is active (or the value of the parameter is large) for the pair of feelings CG, and the feeling parameter H is active (or the value of the parameter is large) for the pair of feelings DH, the blue color associated with the feeling parameter E, the light blue color associated with the feeling parameter F, the green color associated with the feeling parameter G, and the lime green color associated with the feeling parameter H are displayed as the color of the figure R1 . In this case, the region as illustrated is centered and colored using gradation. Note that, in FIG. 24 , coloring and gradation of colors are omitted due to limitations of the drawings.

Furthermore, there may be a plurality of regions associated with active feelings, such as lime green associated with the feeling parameter H in Graphic B of FIG. 24 . According to the magnitude of the value of the feeling parameter, the area of the associated color is displayed large. In this case, the ratio of the values of a plurality of feeling parameters may be displayed in association with the area of the color. Moreover, the shape corresponding to the feeling parameter having the maximum value among the active feeling parameters is displayed as the shape of the figure R1 . As a result, it is possible to intuitively present which feeling is dominant among a plurality of feelings held by the autonomous moving body 10. In this manner, the display form of the figure R1 can be changed according to the type of the feeling parameter and the value of the feeling parameter.

FIG. 25 is a diagram illustrating a display example of the figure R1 and the figure R2 . The figure R1 is as described in FIGS. 14 to 24 . As described with reference to FIGS. 16 and 20 , the figure R2 is a figure (guide) indicating a reference of the shape of the figure. By displaying this figure R2 , a change in the shape of the figure R1 can be easily visually recognized. In this example, in the figure R2 , the feeling parameters included in the pair of feelings described in FIG. 24 are arranged in a place to play a game to each other, and for example, a name indicating the content (type) of the feeling parameter and a value of the feeling parameter are displayed in a part surrounded by a dotted line. As a result, the feelings in a place to play a game are not only playing game regarding the display position but also being able to be associated with the name and the specific number, so that the state of feeling of the autonomous moving body 10 can be more intuitively presented. Note that a display form in which the figure R2 is rotated so that the feeling name and the size can be confirmed from various angles and a display form in which the figure R2 is rotated so that the display corresponding to the feeling parameter having the maximum value is in front of the user observing the autonomous moving body 10 are also conceivable.

FIG. 26 is a diagram illustrating an example in which the display form of the figure R1 changes according to a temporal change in the content (type, value, and the like) of the feeling parameter. FIG. 26 illustrates how the display form of the figure R1 changes in the order of the feeling parameter: B, the feeling parameter: A, the feeling parameter: F, the feeling parameter: C, and the feeling parameter: D. That is, the figure R1 changes as the feeling parameter changes in the order of anticipation, great joy, surprise, great anger, and disgust. In addition to changing the display form of the figure R1 according to an interval at which the content (type, value, and the like) of the feeling parameter temporally changes, the display form of the figure R1 may be changed with the temporally equal interval as the stable interval.

<<Configuration Example of Information Processing Apparatus>>

Here, a configuration in which the information processing terminal 30 realizes the above-described display example will be described with reference to FIG. 10 . The information processing terminal 30 specifies a position (an absolute position in the space, a relative position in the space, a distance to the autonomous moving body 10, and the like) of the autonomous moving body 10 by a sensor unit included in the input unit 310 by sensing the autonomous moving body 10. Note that the sensor unit may be in a form of being built in the information processing terminal 30 as the input unit 310 or in a form of acquiring information used to specify the position of the autonomous moving body 10 from a sensor unit (not illustrated in the drawings) provided outside. The communication unit 350 acquires the feeling parameter stored in the autonomous moving body 10 (or the feeling parameter stored in the information processing server 20) via the network. As described with reference to FIGS. 14 to 26 , the control unit 340 performs control to change the display state (shape, size, color, color combination, movement, and the like) of the figure R1 (the figure R2 as required) to be irradiated (projected) or the figure R1 (the figure R2 as required) to be displayed on the display screen according to the position acquired by the sensor and the content (type, value, and the like) of the feeling parameter acquired by the communication unit 350. Note that, whether to display the figure R2 may be set by a user or the like.

<<Processing Procedure Example of Information Processing Apparatus>>

Next, a procedure in which the information processing terminal 30 realizes the above-described display example (irradiation example/projection example) will be described with reference to a flowchart of FIG. 27 .

In step S1, the information processing terminal 30 specifies the position of the autonomous moving body 10 sensed by the sensor unit. In step S2, the information processing terminal 30 acquires the feeling parameter stored in the autonomous moving body 10 (or the feeling parameter stored in the information processing server 20) via the network. In step S3, the information processing terminal 30 determines the state (type and value) of the acquired feeling parameter.

In step S4, the information processing terminal 30 performs processing of associating the state (type and value) of the feeling parameter with the figure R1 , as described with reference to FIGS. 22 and 23 . For example, the information processing terminal 30 determines whether to display colors in a single color or to display colors in a gradation by combining a plurality of colors. In a case where displaying in a single color, the figure R1 is displayed in the form and color corresponding to the feeling parameter having the largest value. In a case where displaying in a plurality of colors, it is also determined whether or not to associate the figure R1 using the pair of feelings. In a case where the pair of feelings is used, the feeling parameter to be displayed is selected by setting the pair of feelings as described with reference to FIG. 23 . In a case where the pair of feelings is not used, for example, feeling parameters as targets to be displayed are selected in descending order of values of the feeling parameters.

In step S5, the information processing terminal 30 displays the figure R1 on the display screen according to the specified position and feeling parameter.
